VENT-TUBEvATTACHING Application led November To @ZZ whom t may concern:

Be it known that I, JAnns H. COOPER, a subject of the King of Great Britain, residing at Detroit, in the county ofi/Vayne vand State of Michigan, have invented new and useful Improvements in Vent-Tube-Attaching Means for Radiators, of which the following is a specification. 4

This invention relates to radiators for motor vehicles.

The object of my invention is to provide means whereby the upper end of a vent tube may be readily and easily connected with the inside of a filler neck without the use of solder as heretofore, and gain a connection which will not become loose and broken in service, and further leave open the upper end of the vent tube by having no solder to run over and partially or completely close said tube, as heretofore.

In the accompanying drawings illustrating my inventonl Fig. l is a front view of an assembled radiator wherein the upper end of the vent tube is attached to the filler neck in laccordance with my invention;

Fig. 2 is an enlarged vertical sectional view taken through the filler neck and showing in detail the manner in which the vent tube is attached thereto;

Fig. 3 is a top plan view of the structure shown in Fig. l; and

Fig. 4 is a top plan View of the same parts with the fastening tongue shown in position before it is bent to receive the vent tube.

The radiator shown in Fig. l has a core l contained within an outer metal shell or casing 2. These parts are made and assembled in accordance with the usual radia tor practice. The core, through which the cooling water circulates, has the usual upper and lower tanks and the interposed water conduits, either corrugated when of the cellular type or in the form of vertical tubes when of the fin and tube type. It is immaterial to my invention whether the core is of one type or the other, although for illustrative purposes I have shown the fin and tube type in the drawings. The upper tank 3 is shown in Fig. 2, while the vertical tubes el. and horizontal tins 5 are shown in l'. The radiator has a filler neck 6 secured to the top of the upper tank 3 and opening MEANS roza namairons. v

into the same. This neck extends upward through a hole 7 in the top wall ofthe shell 2, as shown in Fig. 2, and as usual in structures of this kind. To close the upper end of the neck 6 there is the usual screw? V6 and held tightly in place.

The tongue 10 is carried by the filler neck 6, as shown, and provides a construction whereby the upper end of the tube 9 is permanently attached to the neck 6 without the use o-f solder as heretofore. Said tongue 10 makes a connection which will not become loose and broken when the radiator is in service as with solder joints, nor is the upper end of the tube 9 partially or fully closed by the solder running over as heretofore. With my connection the tube 9 is maintained open at all times and allowed to function properly as intended.

The tongue 10, as shown in the drawings, is made integral with the upper edge of the neck 6. This is done in the blanking or punching out of the center of the stamping from which the neck 6 is made. in Fig. 4, the tongue 10 in the operation of blanking or stamping out the neck 6 is left integral with the upper edge of the neck and extends diametrically across the same. The second operation in making the neck consists in throwing 'down the tongue parallel with the wall of the neck so as to be in position to allow the vent tube to be slipped over` the has its upper end eX` As shown v tongue and be clamped by pinching, as above having its upper end in said neck, and means carried by said neck and engaging said tube through an opening therein tor holding the tube in said neck.

2. A radiator for motor vehicles, compris-v ing a core having a filler neck, a vent tube having its upper end in said neck, and means carried by said neck and extending into said tube through its upper open en'd for holding said tube in said neck.

3. A radiator for motor vehicles, comprising a core, a iller neck therefor, a vent tube in said core and having its upper end in said neck, a tongue integrally connected with said d neck above the upper end 0I" said tube and extending' downward into the latter for holding the tube against the inside of said neck.

4. A radiator for motor vehicles, comprising a core, a iller neck therefor, a vent tube having its` upper end in said neck, and a tongue formed integral with the upper edge of said neck in the making of the same, said tongue being bent downward substantially parallel with the Wall of said neck and eX- tending into said tube and engaging the same for holding the tube against the inside of said neck.

In testimony that claim the foregoing as my invention, I affix my signature this thirtieth day of October, A. D. 1922.
